Definitions

  • the invention relates to a slide valve with or without a pressure regulator for liquid or gas pipes.
  • a sliding valve intended to stop liquids, gases or vapors circulating in pipes or to regulate the quantity which passes.
  • a slide which is slidable from bottom to top and from top to bottom against one or two valve seats.
  • a valve is designed in which the pressure difference is compensated and no pressure difference acts on the stop elements, whereby the friction force to be overcome, which depends on the pressure exerted, is significantly reduced.
  • This valve mainly comprises a closed body, a supply channel which opens into said body and is connected to the liquid or gas supply pipe, a passage chamber with two walls placed one opposite the other.
  • an evacuation channel which opens on one side into the passage chamber and is connected on the other side to the liquid or gas evacuation pipe, in at least one of the aforementioned walls from the passage chamber an opening which puts the body in communication with the passage chamber, a valve body disposed between said walls and opening for closing this opening, a height-adjustable or pivoting rod to which said valve body is attached, means for adjusting said rod, at least one closure element made of hard material between said valve body and said wall with opening on one side and the other wall on the other side, and at least one elastic element to press one against the other the Said closure elements and the valve body in a water and gas tight manner.
  • valve body By the fact that in the closed position of the valve body the pressure of the incoming liquid or gas acts on both sides of the valve body, a balance is created, as a result of which the valve body is movable independently of the pressure. This effect becomes even more noticeable when the valve body is perforated, so that in the closed position thereof the liquid or gas can freely pass through. In addition, in the event of a sudden production of a pressure difference, the valve body will not be subjected to an impact, so that the fracture of this body will be avoided.
  • the body 1 of the valve with the passage chamber 2, which is provided at the bottom of two parallel walls, in which are arranged two openings 3 located one opposite the other.
  • the passage chamber 2 has an evacuation channel 4.
  • the body 1 has at the top a supply channel 5, so that a liquid or a gas entering through this supply channel into the body is diverted via the openings 3, the passage chamber 2 and the evacuation channel 4 and is evacuated.
  • a screw connection 6 is attached by means of a coupling nut 7 to which the screw connections are connected respectively a supply line and a supply line. evacuation (not shown) of a water or gas pipe.
  • the open upper part of the body 1 is closed by means of a hollow head 8 fixed to the body 1 by means of screws 9.
  • two manometers, respectively 10 and 11, which via a perforation, respectively 12- 13, are in communication with the supply channel 5 and the discharge channel 4 respectively, so that the pressure of the liquid or gas entering and leaving can be controlled.
  • the lower part of the body 1 is closed by means of a bell 14, which is fixed to the body 1 by means of a coupling nut 15.
  • the body has a narrowed part, the two parallel flat walls of which with the openings 3 provided therein are part.
  • a frame 16 with two openings 17 with profiled edge, which openings of the frame adapt to said openings 3, so that the frame is sufficiently tightened.
  • a filter 19 is tightened by means of a sealing ring 18, so that the liquid or the gas is forced to pass through this filter before being evacuated by the evacuation channel 4.
  • a circular closing element 20 preferably made of hard ceramic, which by means of a circular elastic element 21 bears against the inside of the profiled edge of the adjacent opening 17 of the frame 16 that the element in question is axially displaceable and that a good seal is obtained.
  • each annular stop element 20 operates an annular element stop 22, preferably hard ceramic, and which is part of the valve body 35 itself.
  • annular stop elements are housed in an opening 23 in the head of a rod 24 movable in height.
  • Each annular stop element is pushed against its respective annular stop element 20 by an elastic annular element 25, which is placed between this annular stop element and an intermediate ring 26 placed in said head of the rod 24 movable in height .
  • the elastic annular elements 21 and 25 the annular stop elements 20 are strongly pushed one against the other, regardless of the position of the stop elements 22 relative to the stop elements 20. A closure perfect is therefore possible thanks to this.
  • the rod 24 movable in height is fixed in a clamping member 27, which in turn is fixed on a hollow cylinder head 28. Between this hollow cylinder head and the head 8 are placed two pressure springs, respectively 29-30, whose pressure power is chosen so that the valve can only close when the incoming liquid or gas reaches a determined pressure. This part of the valve therefore serves as a pressure regulator.
  • a membrane 31 which completely separates the space in the hollow head 8 from that of the body 1.
  • the space in said head is in communication with the atmosphere by a bore 32 provided in the head.
  • a guide pin 33 forming part of the head freely slides a guide box 34 forming part of the cylinder head 28, so that the cylinder head is effectively guided during its movement.
